tool engaging resilient spring member 8, For the purpose of fuustratmgmy f preferably affixed to the handle 1 by screws 131011: I have shown1n acfompanyulg or other fastening devices 9, extending drawings, a formt e fi at presfgnt through the corresponding longitudinally Preferred yme, Smce 1t W111 g 1n l a extending elongated apertures 10, in one endsatisfactory and reliable results, although it f id i g, as shown inFigure 2. The is to be understood that the various instru- Opposed d fth t l a i Spring 8 mentalities of which my invention consists isrovided with a longitudinal slot 11, can be variously arranged andorganized and thereby forming a bifurcated terminal porthat my inventionis not limited to the pretion. The slot 11 is adapted to engage the 7cise arrangement and organization of these annular groove or channel 7of the tools3 mo or 4, so as to establish a locking engagement betweenthe end of the spring and said tool, while permitting the rotation ofthe latter within said handle 1, as well as with respect to the spring8.

A suitable knob, projection or thumb 12 may be provided on the spring 8so as to facilitate the sliding or displacement of the spring, when itis desired to insert or remove a tool, into or from the handle 1. Thus,to change the tool in the handle, it is merely necessary to withdraw thespring in the direction of the arrow 13, and to withdraw the tool in thedirection of the arrow 14., To insert another tool, the shank of thetool is inserted into the socket 2, and the spring 8 is then moved inthe opposite direction, until the bifurcated or slotted port-ion 11thereof is seated in the annular groove 7 in the upper most portion ofthe tool.

Due to the normal position of the spring 8, (shown in Figures 1 and 2,)the tools 3 or 1 will normally be positioned with the round shank 6thereof disposed in the socket 2. Thus, in the normal position of thetool 3 or 4 with respect to the handle 1, the former is free to rotatewithin the handle in either direction. After the end of the tool,whether the screw driver 3 or the socket wrench 4;, is brought intooperative engagement with the screw, bolt-head or nut, which it isadapted to manipulate, the handle 1 is forced down upon the polygonalshank 5, so as to cause an interengagement between the polygonal shankand the corresponding tool socket 2 in the handle 1, whereupon thedeflection of the handle 1 in either direction will cause acorresponding rotation of the tool, since the tool and handle are thenlocked against any relative rotation with respect to eachother. If it isdesired to return or deflect the handle back into an initial position,without rotating the tool, the pressure on the handle 1 is relieved,whereupon the spring 8 withdraws the handle in an upward directionrelative to the tool 3 or 4, thereby positioning the round shank 6within the socket 2, so as to permit the relative rotation of the tooland handle. This operation may be effected in either one of twodirections.

It will thus be seen that by my novel construction, a tool may beprovided of a simple and inexpensive, yet e'lficient form, wherebyintermittent rotary motion may be imparted to a tool, in eitherdirection, while the tool is in constant operative engagement with thescrew or other element being manipulated, by means of a handle or holderwhich normally carries the tool in a revoluble manner r and which can becaused to engage a tool in a non-revoluble manner at will.

It will now be apparent that I have devised a new and useful rotary toolhandle and tool therefor, which embodies the features of advantageenumerated as desirable in the statement of the invention and the abovedescription, and while I have, in the present instance,

shown and described a preferred embodiment thereof, it is to beunderstood that such embodiment is susceptible of variation in variousparticulars without departing from the spirit or the scope of theinvention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

In a device of the character stated, an elongated handle member having apolygonal shaped socket therein, a tool having two adjacent shanksadapted to be positioned alternatively within said socket, one of saidadjacent shanks being round to revolubly fit said polygonal socket, saidother adjacent shank being polygonal to non-revolubly fit said polygonalsocket, thereby alternatively to dispose said tool in revoluble ornon-revoluble relation to said handle member, there being an annulargroove in said tool, a generally flat spring slidably mounted upon saidhandle member, having a bifurcated end adapted revolubly to engage insaid corresponding annular groove in the end of said tool when spring isin its forward or operative position thereby detachably to maintain saidtool in assembled relation to the tool holder and normally yieldably tomaintain said tool in revoluble relation with respect to the holdermember.

In testimony whereof, I have hereunto set my hand.

JAMES P. SALMON.
